This study attempts to discover a differentiated service strategy for the hotpot restaurant industry from the perspective of Chinese Generation Z customers, as well as to further explore the inner needs of Chinese Generation Z to make practical implications for discovering the method of gaining their satisfaction and loyalty. This paper employs questionnaires to collect analytical data and through a case study to produce company strategies. Smith's Marketing Ethics Sequential System Model (SMESSM) is introduced in this paper for the decision of whether the case study company Haidilao Hot Pot should make a new strategy on service based on Generation Z's consuming behavior. The findings of this study demonstrate that hotpot restaurant must differentiate their services for Generation Z from older generation customers to gain a sustainable development of the hotpot business. Proper differentiated service will not only improve Generation Z's dining experience but also reduce costs. This paper is the first to discuss differentiated service strategy in the hotpot restaurant business from the perspective of Generation Z customers. And a Chinese experience of SMESSM for practical use is introduced in this paper, which enriches the relevant implications for future research on business strategy.

Recent advances in low-cost remote monitoring systems have made it possible and practical to perform structural health monitoring (SHM) on a large scale. However, it is difficult for a single remote monitoring system to cover a wide range of SHM applications due to the amount of specialization required. For the remote monitoring system to be flexible, sustainable, and robust, this article introduces a new cost-effective, advanced remote monitoring and inspection system named DuraMote that can serve as a next generation supervisory control and data acquisition (SCADA) system for civil infrastructure systems. To evaluate the performance of DuraMote, we conduct experiments at two representative counterpart sites: a bridge and water pipelines. The objectives of this article are to improve upon the existing SCADA by integrating the remote monitoring system (i.e., DuraMote), to describe a prototype SCADA for civil engineering structures, and to validate its effectiveness with long-term field deployment results.

Recently high-speed memory array based on RAM, which is a type of solid-state drive (SSD), has been introduced to handle the input/output (I/O) bottleneck. But there are only a few performance studies on RAM based SSD storage with regard to diverse workloads. In this paper, we focus on the file system for RAM based memory array based NGS (Next Generation Storage) system which is running on Linux operating system. Then we perform benchmark tests on practical file systems including Ext3, ReiserFS, XFS. The result shows XFS significantly outperforms other file systems in tests that represent the storage and data requests typically made by enterprise applications in many aspects. The experiment is used to design the dedicated file system for NGS system. The results presented here can help enterprises improve their performance significantly.

It is a right time to improve the Korea Foreign Trade Act(KFTA) as a fundamental law on Rules of Origin(RoO) in the global trade circumstances which are summarized FTA and WTO. The KFTA's RoO constitutes the labelling system of the Country of Origin, the criterion of it, the issuing of certificate of origin and the punishing offender mainly around the importing goods. This study has focused on the problems of KFTA's RoO at the macro and practical level, and proposed the programs to improve the KFTA's RoO about importing, exporting and domestic production goods. KFTA need to create a purpose clause to protect consumers and industries also, and has to be located a general and top position in the RoO of Korea. In the concrete, the labelling system of the Country of Origin has to set limited in the point of minimum necessity view. The criterion of the Country of Origin also has to improve the wholly obtained criterion, the changing in tariff classification criterion, value added criterion and processing operation criterion to harmonize WTO Rules of Origin and FTA Rules of Origin. The punishment ceiling against offender has to raise to guarantee the effectiveness of RoO.

In wireless communication, the multiple-input multiple-output (MIMO) system is a well-known approach to improve the reliability as well as the data rate. In MIMO systems, channel state information (CSI) is typically required at the receiver to detect transmitted signals; however, in practical systems, the CSI is imperfect and contains errors, which affect the overall system performance. In this paper, we propose a novel maximum likelihood (ML) scheme for MIMO systems that is robust to the CSI errors. We apply an optimization method to estimate an instantaneous covariance matrix of the CSI errors in order to improve the detection performance. Furthermore, we propose the employment of the list sphere decoding (LSD) scheme to reduce the computational complexity, which is capable of efficiently finding a reduced set of the candidate symbol vectors for the computation of the covariance matrix of the CSI errors. An iterative detection scheme is also proposed to further improve the detection performance.

Purposes: This study aims to identify the characteristics of the study subjects by age, including non-elderly people aged 19 to 65, pre-elderly people aged 65 to 75, and elderly people aged 75 and over, and to identify factors affecting health literacy based on an investigation of the health literacy level of each study group. This study would like to find out the differences in health literacy factors by age group. Methodology: The HLS-EU-Q16, developed by the World Health Organization Regional Office for Europe for the Health literacy Survey of Europeans, will be applied in this study. Findings: We found that scores decreased in order of nonelderly, pre-elderly, and late-elderly in health care, disease prevention, and health promotion. In addition, health literacy was lower in the older age group, and higher health literacy was associated with being unmarried, higher education, and higher income. In terms of influencing factors, marital status was significantly different in the non-elderly group, and higher education level was associated with higher health literacy. Practical Implications: The results of this study show that health literacy levels are low in all age groups, and efforts to improve health literacy in younger, older, and non-elderly groups are needed. It is expected that age-specific health literacy strategies can help improve the level of understanding and utilization of health information, improve health, and lead a healthy life.

This study is to explore one of efficient procedures in producing English textbooks for secondary school students. According to a series of changes in the National Curriculum, new textbooks have been selected and used in English classes. Textbooks are one of the fundamental factors in teaching and learning languages together with learners and teachers. So this study emphasizes the significance of textbooks and presents the practical model of producing English textbooks including activity books, from major aspects such as planning, writing, editing, selecting, etc. The current government has made continuing efforts to improve English education development by administrating innovative policies [strategies]. However, there still remain lots of difficulties in this gigantic task, which is not an exception in the matter of textbooks. Therefore, to provide students with better textbooks, the government should not only invest great funds but also renovate the present polluted system of selecting textbooks.

Network coding is promising to maximize network throughput and improve the resilience to random network failures in various networking systems. In this paper, the problem of providing efficient confidentiality for practical network coding system against a global eavesdropper (with full eavesdropping capabilities to the network) is considered. By exploiting a novel combination between the construction technique of systematic Maximum Distance Separable (MDS) erasure coding and traditional cryptographic approach, two efficient schemes are proposed that can achieve the maximum possible rate and minimum encryption overhead respectively on top of any communication network or underlying linear network code. Every generation is first subjected to an encoding by a particular matrix generated by two (or three) Vandermonde matrices, and then parts of coded vectors (or secret symbols) are encrypted before transmitting. The proposed schemes are characterized by tunable and measurable degrees of security and also shown to be of low overhead in computation and bandwidth.
